ABSTRACT:
An improved rolling element bearing assembly is provided which is particularly applicable for use in gas turbine engine gearboxes. The rolling element bearing includes an inner ring mounted to a rotatable shaft and an outer ring mounted to a stationary structure. The inner and outer rings define a raceway for a plurality of rolling elements. The rolling element bearing assembly includes the bearing and a compliant anti-rotation ring compressed between the bearing outer ring and the stationary structure. The compliant ring provides improved frictional engagement and improved bearing damping between the bearing outer race and the stationary structure preventing outer ring rotation within the stationary housing.
